And does the inverse being at 35% mean that you get 35% of the value of the inverse or that you can only get up to 35% of the total inverse in jp of the tech Or does it mean something else all togther ? Its a bit of a mystery to me .

No, you take something that gives you a benefit (For example +1 to hit) and turn it around so you suddenly have -1 to hit. Lets say that +1 to hit would normally cost 3 JP, so now you take 35% of 3 =1, and you get 1 additional JP to use on your jutsu.

Ahhhhh okay so the -5 from lost turn , condtional and all that still is in play , its just being "debated" gotcha. I thought the limit on "inverse" bonus was refering to "total" Allowed minus's applying to jutsu . It's referring just to the inverse . My bad then !
